The ADV7184 is a single‑chip multiformat video decoder that automatically detects and converts PAL, NTSC, and SECAM standards from composite, S‑Video, and component inputs into a digital ITU‑R BT.656 format. It features four 10‑bit ADCs, a 12‑channel input mux, and a flexible 2‑wire I²C‑compatible serial interface for configuration.
The device includes integrated antialiasing filters, adaptive digital line‑length tracking, macrovision detection, and VBI data recovery. It is supplied in an 80‑lead LQFP Pb‑free package and operates over an industrial temperature range of –40 °C to +85 °C.
